Reliability and validity testing of the Chinese version of Combined Outcome Measure for Risk Communication and Treatment Decision-Making Effectiveness in family members of ICU patients
Objective To translate the Combined Outcome Measure for Risk Communication and Treatment Decision-Making Effectiveness（COMRADE） to Chinese，and test the reliability and validity of the Chinese version of the scale in the families of critically ill patients. Methods The English version of COMRADE was translated into Chinese according to the Brislin translation model and culturally adjusted to ensure its semantic and cultural applicability. A convenience sampling method was employed to select 450 family members of patients in the ICUs of a tertiary class A general hospital in Zhejiang Province between April and August 2024 for the purpose of assessing the reliability and validity of the scale. Results The Chinese version of the COMRADE contained 2 dimensions of risk communication and decision effectiveness，with a total of 20 items，and the content validity of the scale was 0.96. The factor analysis extracted 2 common factors，and the cumulative variance contribution rate was 63.67%. The total Cronbach’s alpha coefficient of the scale was 0.842，with folded reliabilities ranging from 0.701 to 0.749. Validation factor analysis showed a good model fit（χ2/df=2.143，RMSEA=0.068，CFI=0.920，TLI=0.910）. Conclusion The Chinese version of the COMRADE scale has been demonstrated to possess both reliability and validity，and thus represents a valuable tool for the assessment of the effectiveness of risk communication and decision-making processes among ICU family members in the context of alternative medicine.
